Earlier I thought they both perform the same actions like opening a link to a new tab (or window ) in the browser. But, just removing the underscore can make an important difference.

The target attribute specifies where to open the linked document.

Example

<a href="https://www.google.com" target="_blank">Visit google Site</a>

With target=_blank,

Whenever we click the link, it will open in a new tab. So, let's say if we click more links then, every time a new browser tab will open which can create multiple tabs, and maybe it can frustrate the user and its experience.

Alternate solutions we can use target=blank,

Now, let's remove the underscore, then the browser will open the link in a tab called 'blank' instead of opening a new one. With this, if the user will click multiple links then the links will open in a single tab.

Example

<a href="https://www.google.com" target="blank">Visit google Site</a>

Demo

{% codepen codepen.io/nirazanbasnet/pen/wvJOgvW %}
